If the response is: compile on a fast machine, execute also on a slow one, then I think it's worth also for scipy/numpy.

Right. Hence my question about dependents. Deploying to a machine that
is different to the build machine has never really been supported.
People packaging binaries build with MacPorts were still interested in
that even back when universal meant i386/ppc, of course.
